[#500] The discharge over a rectangular weir, considering the velocity of approach, is (where H 1 = H + H a ) (H 1 = Total height of water above the weir, H = Height of water over the crest of the weir and H a = Height of water due to velocity of approach)
Correct Answer
(B) $$frac{2}{3}{{ ext{C}}_{ ext{d}}} imes { ext{L}}sqrt {2{ ext{g}}} left[ {{ ext{H}}_1^{frac{3}{2}} - { ext{H}}_{ ext{a}}^{frac{3}{2}}}
